The shredder consists of a set of rotating blades, paper combs, and driving motors. The paper is sent from the middle of the biting blade and divided into tiny pieces of paper to keep it secret. Paper fragmentation refers to the shape when the paper is chopped by a shredder after a shredder. According to the composition of the shredding knife, the existing shredding paper methods are: broken, granular, segment, foam, strip, filaments, etc.
Now the paper shredder, in addition to the paper processing, can also cut credit cards, optical discs, etc.
Paper dding capacity refers to the thickness and maximum number of paper the shredder can handle at a time, while the amount of shredding is the throughput of the piece itself. General paper shredders can break 13-15 pieces per time, large paper shredders can break 60-70 pieces per time. Generally, the better the paper shredding effect, its paper shredding ability is relatively poor. For example, the nominal paper shredding ability on a brand of paper shredder is A4,70g and 7-9 pieces, which means that the paper shredder can handle seven to nine pieces of A4 pieces with a chopped thickness of 70g at a time. General office to choose A4,70g, 3-4 pieces can meet the daily work needs, if it is a large office needs to choose the appropriate size and faster speed of the paper shredder. Existing large paper shredders generally reach 60-70 pieces per time.
Paper shredding must be used according to the shredding capacity that the machine can bear, so as not to lead to abnormal machine paper, motor load is too large burning and other situations.
Paper crushing effect refers to the size of the waste paper formed by the paper after the paper shredder treatment, which is generally measured in mm (mm). Grain, foam shape effect is the best, broken shape second, bar, segment shape relative effect is worse. For example, 2 * 2mm confidentiality effect can cut A4 paper into more than 1500 small pieces. Different occasions can choose different shredders of shredder according to actual needs. If the home and small offices do not involve confidentiality occasions can choose 4mm * 50mm, 4mm * 30mm and other specifications can be. According to the minimum standard of destruction data, computer printed documents must be broken to 3.8mm. For highly classified documents, horizontal shredders shall be used, preferably to achieve the effect of 3mm * 3mm and below.
